Hair testing is recognized as an effective method for uncovering drug and alcohol consumption. The growing hair strand captures biomarkers, offering a prolonged timeline of substance usage. Hair retrieved near the scalp can yield a detection period of up to three months for both alcohol and other substances. It is easy to obtain, resistant to tampering, and simple to transport.
A 1.5-inch section comprising approximately 200 hairs (similar in thickness to a #2 pencil) taken closest to the scalp produces around 100mg of hair, the perfect amount for testing. For EtG, additional tests, and any screenings surpassing ten panels, a 150mg sample is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. If scalp hair is not available, an equivalent quantity of body hair can be utilized. "Head hair" denotes only scalp hair, while "body hair" encompasses all other types (e.g., facial or axillary hair).
Process Overview
The core stages in the lab processing for a drug test are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a lab's system. This step ensures the sample's proper sealing and shipping, generates a random LAN (Laboratory Accessioning Number), and completes remaining data entry if not handled by an electronic system.
Screening entails a preliminary drug abuse assessment. Though it is a practical approach to dismiss drug use in most cases, positive screenings require affirmative confirmation to be court-admissible. Samples showing presumptive positive results in Screening demand further confirmation.
In the event a specimen returns a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at a significantly lower concentration than in other methodologies (such as urine or oral fluid testing), making hair drug analysis the most challenging procedure.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS technologies. Samples indicating presumptive positive findings are washed for Confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
